Thanks bentleyjames52, Forzen 's digipak ost. price in Ebay

From the info on this site, it looks like the digipack is a 2-disc
deluxe version (with tons more music). Despite the cheaper
packaging the manufacturer probably feels justified in charging a
higher price for this version than the 1-disc. However, given it's
ebay people can charge what they like; if someone bids that price
because they don't mind paying it, that's what it will sell for.

Could also be an import copy, so only available in certain countries
in that format, and again the seller has deemed that sufficient to
increase the price because of the relative rarity factor.
